I decided to play a few games to showcase PGXP as well, Blasto!, MediEvil and Jersey Devil (with Metal Gear Solid on the way maybe later tonight or tomorrow).
Blasto! may be one of the most difficult games to play on an emulator with high resolution/quality settings. I wager it'd bring most computers that aren't truly modern or run nice intel processors to their knees, as it did with mine. The slowdowns get worse as the game goes on because the fully 3D environments take up more screen space and get complex too....
MediEvil is a great game and has barely any slowdowns, looks great and sounds great. CPU Overclocking breaks this game.
Jersey Devil is another fun one, I call it platforming hell because it can be really difficult with some jumps that you should clearly be able to make........... Looks amazing though.
Blasto breaks in CPU+Memory mode, so don't use that.
MediEvil was fine I believe, also Vertex Caching worked without issues.
Jersey Devil I can't remember too much, but CPU overclocking is allowed, and I had Memory Mode with no Vertex Caching, because I think vertex caching tends to break 2D elements often.

Audio might be a little loud, but nothing "too" bad, sorry in advance though.
Edit: Oh, since we're talking about recording settings, I too use Fraps, to make things easier, disable Force RGB Loseless Recording, that setting is a killer. My Jersey Devil video of 15 minutes came out to 33GB of data..... 33!!!!!!! I had to re-encode it to a much more sane 1 GB or something around there, but that's just silly.
I record at 1360*1020, keeps the 4:3 aspect ratio (I play all games like that). I don't think it affects me too much when I record in either 30 or 60fps.
Edit x2: Won't showcase Metal Gear Solid, I can play with high settings, but enabling xBRZ makes the water scenes run abysmally slow =(. Game looks gorgeous.... maybe I'll just show it with the standard PlayStation styled textures going on.......
Tip for those playing MGS, CPU+Memory Logic mode seems to be the best way to make everything nice and stable, but it is a bit of a performance sink.
I typically play games that I don't use xBRZ in at 8x8 in ResHack, it seems to be a bit too much for Metal Gear Solid with CPU+Memory Logic mode.
